The electric pasteurizer

摘要

The development of pasteurization is traced in this article from the experiments with wine by Louis Pasteur to the modern methods of milk pasteurizing — the holder and the high-temperature short-time methods. In the latter method electricity or hot water is used. Control, vital to the success of the process because of the necessity of holding the temperature within very close limits, is discussed in some detail as it operates in the present-day electric unit.
